STEAM-LUBRICATOR.

Specification of Letters Patent.

Patented July 23, 1912.

Application filed December 16, 1907. Serial No. 406,819.

To all whom it may concern.

Be it known that I, AUGUST MLITZ, a subject of the German Emperor, residing at Charlottenburg, near Berlin, Germany, have invented new and useful Improvements in Steam-Lubricat-ors, of which the following is a specification.

This invention relates to a steam lubricator in which the different working positions are adapted to be controlled by means of a single lever or the like.

In the present construction of the steam lubricator, there is a valve which for conducting the steam, is provided internally with longitudinal bores leading from the front and communicating with a small number of transverse ports. These longitudinal bores replace a number of transverse ports and grooves, which would otherwise be required. Owing to the less number of the transverse ports and grooves, the diameter as well as the length of the valve may also be smaller without increasing the difficulties in connection with the manufacture of the valve. The steam, which drives the lubricant out of the oil reservoir into the conduits in which it is to be used, must with this arrangement of the bores be admitted in the longitudinal direction of the conical valve from the larger, outer end of the same, whereby it is necessary to provide an auxiliary steam-chamber in front of the valve. The steam in this steam-chamber acting on the larger end of the valve always presses the valve tightly upon its seat. The valve can however be easily moved owing to its small size.

The accompanying drawing shows the construction of my double-sided new steamlubricator.

Figure 1 is a vertical section through the middle of the lubricator, Fig. 2 a vertical section in a plane at right-angles to the section according to Fig. 1 through the middle of the lubricator, Fig. 3 a horizontal section through the lubricator in the plane of the valve, Fig. 4 a side elevation of the conical valve on an enlarged scale, Fig. 5 a plan view of the valve, and Fig. 6 is a longitudinal section of the valve on the line AB in Fig. 5; Figs. 7, 8, 9 are cross sections of the valve on the lines OD, EF, G-H respectively in Fig. 4.

Referring to the drawing a indicates the oil-reservoir, b the valve on a-shaft 0, which valve can be adjusted by means of a lever cl.

f is the main steam chamber communicating by means of a pipe 9 with the auxiliary chamber h at the larger, outer end of the valve. The auxiliary chamber h is closed by a screw 2'. As can be seen from Fig. 3 the ducts 70 lead through the casing of the oil-reservoir to the valve 2').

Z are passages for the outflow of oil from the doublesided apparatus to the point of use. The spindles g, each carrying a hand wheel are adapted to adjust the two sightfeed delivery ports, and the screws m to adjust two auxiliary delivery ports leading directly to the passages Z. The latter must be opened if more oil is required for a shorttime.

As will be seen from Fig. 4, the valve 6 has two pairs of longitudinal bores, one pair for each side of the apparatus, of which the upper bores 79 are open at the larger outer end of the valve and the lower 0 are closed by plugs. In the illustrative embodiment the bores 0, j) on each side converge and communicate with each other at their ends in the interior of the valve. In the valve 6 there are also transverse bores 1* and 8 communicating with the longitudinal bores 0 and a transverse bore 4; communicating with the main chamber f and the oil reservoir a. The transverse bores r, s and o communicate with grooves 1' 8 'w, of the valve in order to maintain the communication of the bores of the valve with the corresponding bores and channels in the difierent posit-ions of the valve.

When the valve assumes'the position as shown the steam enters the oil-reservoir from the main steam chamber 7'' and passes through the tube a, the groove w, the bore 1; of the valve and the tube 00 to the bottom of the oil-reservoir and is condensed therein. The oil is conducted from the oil-reservoir through the tubes 71. past the regulatingscrews 9 and drop by drop through the glasses t whence it flows through the ducts in to the ports 8 of the valve and to the ports 1 whereupon it is drawn away by the steam, the latter passing from the auxiliary steam chamber it through the bores 19 and 0 to the ports 1* and past the ports 8. The mixture of oil and steam is conducted from the ports a" to the tubes Z and from there into the oil conduits leading to the points of use.

If the lubricator of the above described construction is to be stopped, the valve is turned in such a way that both the steam and the oil outlet are closed from the inside of the valve, so that, in spite of the steam in the auxiliary chamber h continuing to act on the valve, the oil can no longer get into the oil conduits leading to the points of use Z and even the oil contained therein is entirely stopped whereby a considerable saving of oil insured. A further advantage oi the described lubricator resides in the fact that, on the valve being set to work again, the steam at once begins to operate again and the drops are delivered, without any necessity of adjustment, exactly in the same manner as before the stoppage.

l i hat I do claim as my invention, and desire to secure by Letters Patent, is

l. A steam lubricator comprising an oilreservoir, means for conducting steam into the reservoir, means for conducting oil out of the reservoir and tubes for tile outflow of oil to the points of use in combination with a conical valve provided with a longitudinal channel having an open outer end, and two transverse ports, the first of said ports communicating with the means for conducting oil out of the reservoir and with the longitudinal channel, the second of said ports communicating with the longitudinal channel and with the tubes for the outflow of oil, means for conductingstem to the larger end of the valve and means adapted to turn the valve for starting or stopping the lubricator substantially as and for the purpose set forth.

2. A steam lubricator comprising an oilreservoir, means for conducting steam into the reservoir, means for conducting oil out of the reservoir and tubes for the outflow of oil to the points of use in combination with a conical valve provided with a longitudinal channel formed by two bores, one of said bores having an open outer end, the second longitudinal bore having a closed outer end, the bores being in communication at their inner ends, and with two transverse ports, the first of said ports communicating with the means for conducting oil out of the reservoir and with the second longitudina bore, the second of said ports coin- Inunicating with the second longitudinal bore and with the tubes for the outflow of oil to the points of use, means for conducting steam to the larger end of the valve and means adapted to turn the valve for starting or stopping the lubricator substantially as and for the purpose set forth.
